This is awesome! It's tempting to pull this into Construct 3 and make a scrolling version with names when you mouse over characters. I love that Stan from Nightmare Cops made it in there, along with the red knight from Castle Crashers, Alien Hominid, Meat Boy and tons others!
The Gradius and R-Type ships are badass and there's always a special place in my heart for the Metal Slug tank too. Great work!
